This is the ceiling of the entrance hall to the University of Copenhagen's Ceremonial Hall (click to embiggen).
It's an astronomical theme, zodiacal figures surround the central figures (you really need to embiggen them to get a good view) which are .... well, I don't actually know. I think that it's the Moon attended by Venus, but I could be wrong. There wasn't any information in the entrance way itself about the ceiling (that I saw), and there seems to be nothing online.
It didn't help that most of the University was destroyed in 1801 by English bombardment, so the information of the ceiling may have been lost.
But hey, it looks great though.
